I have put my Ranger on so many different straps, and I've loved it on all of them, but after about a day I go back on the bracelet which I have basically accepted as integrated at this point. I got a Vario bund that looks quite nice. an MN style from CNS, and a grip of NATOs, a single pass leather, some canvas. I stopped trying. The Ranger stays on its bracelet for me. Additionally I asked my AD about getting the OEM NATO. He said it was $175, and I still consider it but I know it'll be right back on it's bracelet in a few minutes so I've resisted thus far.
And special love to the other weirdos on here with Rangers, @neomatik and @TimeCop it's a nearly perfect watch for me.
